I have upgraded all my machines from 'utopic' (with linux 3.16) to 'vivid' (with linux 3.19) where this bug is fixed. So, I do not PERSONALLY need a backport.
But this bug still exists for 'utopic', and perhaps even LTS 'trusty'. So, it is possible that this bug needs a backport to 'utopic' and LTS 'trusty'. For 'utopic' and LTS 'trusty', this bug may be closed only AFTER : - a backport corrects the problem (then the status would be " Fix Released") or - the Ubuntu release has reached its end of life (then the status would be "Won't Fix'). Anyway, this bug is perfectly valid, and its status must NOT be set to "Invalid". -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1396840 Title: 10de:0867 [iMac9,1] Module nouveau systematically crashes after a few minutes, whereas module nvidia from nvidia-331-updates crashes only after several hours of work Status in linux package in Ubuntu: Incomplete Bug description: Module 'nouveau' systematically crashes after a few minutes, whereas module 'nvidia' from 'nvidia-331-updates' crashes only after several hours of work. $ uname -r 3.16.0-25-generic $ dpkg-query -W 'linux-*image-*3.16.0-25*' linux-image-3.16.0-25-generic 3.16.0-25.33 linux-image-extra-3.16.0-25-generic 3.16.0-25.33 linux-signed-image-3.16.0-25-generic 3.16.0-25.33 $ lsmod | head -1 ; lsmod | grep '^nouveau' Module Size Used by nouveau 1234845 3 $ sudo lspci -nn -vv -s 03:00.0 03:00.0 VGA compatible controller [0300]: NVIDIA Corporation C79 [GeForce 9400] [10de:0867] (rev b1) (prog-if 00 [VGA controller]) Subsystem: Apple Inc. iMac 9,1 [106b:00ad] Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx+ Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0, Cache Line Size: 256 bytes Interrupt: pin A routed to IRQ 45 Region 0: Memory at d2000000 (32-bit, non-prefetchable) [size=16M] Region 1: Memory at c0000000 (64-bit, prefetchable) [size=256M] Region 3: Memory at d0000000 (64-bit, prefetchable) [size=32M] Region 5: I/O ports at 1000 [size=128] Expansion ROM at d3000000 [disabled] [size=128K] Capabilities: [60] Power Management version 2 Flags: PMEClk- DSI- D1- D2- AuxCurrent=0mA PME(D0-,D1-,D2-,D3hot-,D3cold-) Status: D0 NoSoftRst- PME-Enable- DSel=0 DScale=0 PME- Capabilities: [68] MSI: Enable+ Count=1/1 Maskable- 64bit+ Address: 00000000fee0300c Data: 4152 Kernel driver in use: nouveau ProblemType: Bug DistroRelease: Ubuntu 14.10 Package: linux-image-extra-3.16.0-25-generic 3.16.0-25.33 ProcVersionSignature: Ubuntu 3.16.0-25.33-generic 3.16.7 Uname: Linux 3.16.0-25-generic x86_64 NonfreeKernelModules: wl ApportVersion: 2.14.7-0ubuntu8 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: urbah 3073 F.... pulseaudio CurrentDesktop: GNOME Date: Thu Nov 27 02:05:32 2014 HibernationDevice: RESUME=UUID=d78e46a2-825e-4ad0-8f14-c7d2935c33c7 InstallationDate: Installed on 2014-11-03 (23 days ago) InstallationMedia: Ubuntu-GNOME 14.10 "Utopic Unicorn" - Release amd64 (20141022.1) MachineType: Apple Inc. iMac9,1 ProcFB: 0 nouveaufb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.16.0-25-generic.efi.signed root=UUID=b587542c-4076-491a-ae4d-21942b20daf6 ro quiet splash vt.handoff=7 RelatedPackageVersions: linux-restricted-modules-3.16.0-25-generic N/A linux-backports-modules-3.16.0-25-generic N/A linux-firmware 1.138 SourcePackage: linux UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 04/27/09 dmi.bios.vendor: Apple Inc. dmi.bios.version: IM91.88Z.008D.B08.0904271717 dmi.board.asset.tag: Base Board Asset Tag dmi.board.name: Mac-F2218FC8 dmi.board.vendor: Apple Inc. dmi.chassis.asset.tag: Asset Tag# dmi.chassis.type: 13 dmi.chassis.vendor: Apple Inc. dmi.chassis.version: Mac-F2218FC8 dmi.modalias: dmi:bvnAppleInc.:bvrIM91.88Z.008D.B08.0904271717:bd04/27/09:svnAppleInc.:pniMac9,1:pvr1.0:rvnAppleInc.:rnMac-F2218FC8:rvr:cvnAppleInc.:ct13:cvrMac-F2218FC8: dmi.product.name: iMac9,1 dmi.product.version: 1.0 dmi.sys.vendor: Apple Inc.
